Digital Images

I already knew how to crop and resize pictures, although I did not know about the different formats (JPEG, GIF, etc and rastor vs. vector) or about the different copyright laws. That will be very useful information, because unless or until I am able to tour Europe and visit all the Roman archaeological sites and all the museums with Roman artifacts, I will have to use pictures which others took. In addition, scholars often make reconstructions of buildings and archaeological sites, and those images could be very useful to show my students, so that they can see what something would have looked like. (For example, few people realize that Greek and Roman statues were actually painted in bright colors rather than left as bare marble. Pediments on old temples look completely different when they are filled with eye-popping color.) Happily, fair use means that I can use as many pictures as I want within my classroom, even if I can't post them online or share them with other teachers later.
